It's good to hear about developments that use blockchain technology as it was intended to be used, distributed and decentralised.Interesting view on blockchain’s real-world applications in FLOSS Weekly #442 from earlier this year.
The guest project is Hyperleger, which has some big hitters associated with it.
So many organisations (particularly in the finance/banking sector) talk of their centralised blockchain developments. Without the decentralised aspect, a blockchain is merely a database, one which retains all the vulnerabilities of traditional centralised databases. What's remarkable about blockchain technology is that it enables a decentralised ledger to be built with many, many copies of the data distributed across the network, providing incredible resiliency and eliminating any single point of attack. And yet, at the same time, it can be used by anyone and everyone without requiring a central authority to validate transaction data.
